Bruised toenail.

I have a bruised toenail. I didn't even know it was possible to bruise your toenail until mine turned all kinds of weird colours. I have no idea how I hurt it, but it's been this way for several weeks, and according to Google all I can do is wait 5 months for it to grow out! I don't want to wait 5 months!!!! If there are any other options, please tell me! (Note- not if it involves surgery or anything gross!!!) Ahhh I'm not patient! And it didn't help that Mum stepped on it yesterday. I tried putting ice on it, but in this weather, the cold ice hurts more than the bruise itself. :(
